[0002] In the fields of oil extraction, geological exploration and groundwater research, drilling is of great significance. Traditional drilling detection equipment has prominent problems when used for deep groundwater pollution monitoring. It can only detect and sample at a specific fixed depth, with poor flexibility, complex drilling strata, and different causes of groundwater pollution at different depths. Shallow layers are easily affected by surface industrial wastewater leakage and agricultural non-point source pollution, while deep layers are often contaminated by formation mineral seepage, residual pollutants from historical oil extraction, etc. Because it is impossible to continuously monitor different depths, it is difficult to accurately grasp the vertical distribution of pollution, resulting in inaccurate pollution assessment and lack of accurate data when formulating treatment plans, protecting resources and drilling planning. In addition, with increasingly stringent environmental protection requirements, higher requirements are placed on the accuracy and comprehensiveness of groundwater pollution monitoring, which are difficult to meet with traditional devices. Therefore, it is imperative to develop a device that can sample and detect water at different depths in the well. Therefore, a deep groundwater pollution monitoring device is urgently needed.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 to Figure 4 In an embodiment of the present invention, a deep groundwater pollution monitoring device includes a mounting base 1, which is in a circular ring shape. An upper disc 2 is arranged above the mounting base 1, and the upper disc 2 is fixedly connected to the mounting base 1 through a plurality of connecting arms, and the plurality of connecting arms are distributed in a circumference. A driving motor 3 is fixedly installed on the upper end of the upper disc 2, and a first recovery wheel 4 is fixedly connected to the output end of the driving motor 3 through bolts. A first pull rope 5 is wound around the outer wall of the first recovery wheel 4, and the first pull rope 5 is made of nylon, and the nylon material has good corrosion resistance and high temperature resistance, and is durable. The free end of the first pull rope 5 is fixedly connected to a submersible mounting bucket 6, and a counterweight is arranged below the submersible mounting bucket 6. Block 7, and the counterweight block 7 is conical, so that the resistance in the water can be better reduced during the diving process. The counterweight block 7 is made of metal, has a large weight, a small volume, and is easy to carry. A trigger mechanism 101 is fixedly installed between the counterweight block 7 and the diving installation barrel 6. Four groups of sampling tubes 9 are fixedly connected to the outer wall of the diving installation barrel 6 by bolts, and the four groups of sampling tubes 9 are distributed in a circle on the outer wall of the diving installation barrel 6. Each group of sampling tubes 9 is fixedly connected to the submersible installation barrel 6 through a sampling mechanism 201. When the submersible installation barrel 6 dives in the water, as the depth of the water deepens, the trigger mechanism 101 will trigger the sampling mechanism 201 for sampling according to the depth of the submersible installation barrel 6 in the water.

[0036] Example 2: Please refer to Figure 3 to Figure 5The trigger mechanism 101 includes a submersible ball 10, which is made of rubber and has good elasticity. When the submersible ball 10 enters the water, it is more fully subjected to water pressure and can shrink better. The submersible ball 10 is fixedly connected to the submersible installation barrel 6 through a pipeline. The bottom of the submersible installation barrel 6 is fixedly connected to a limit frame 33, and the outer wall of the submersible ball 10 abuts against the inner wall of the limit frame 33. The limit frame 33 can limit the submersible ball 10 to prevent the submersible ball 10 from running off. Four groups of abutment circular plates 14 are arranged inside the submersible installation barrel 6, and the four groups of abutment circular plates 14 are aligned from top to bottom inside the submersible installation barrel 6. A plurality of first elastic telescopic rods 13 are fixedly connected to the top of the inner wall of the submersible installation barrel 6, and the output ends of the first elastic telescopic rods 13 are respectively fixedly connected to the upper ends of the four abutment circular plates 14;

[0037] See also Figure 4-5 , the inner wall of the submersible installation barrel 6 is slidably connected with a first piston plate 16, and the outer wall of the first piston plate 16 is fixedly connected with a sealing ring, which is also made of rubber material. The outer wall of the sealing ring abuts against the inner wall of the submersible installation barrel 6. When the inside of the submersible installation barrel 6 is filled with gas, the first piston plate 16 will be pushed, and the sealing ring can effectively enhance the sealing between the first piston plate 16 and the inner wall of the submersible installation barrel 6. A plurality of groups of second elastic telescopic rods 15 are fixedly connected to the bottom end of the inner side of the submersible installation barrel 6, and the telescopic end of the second elastic telescopic rod 15 is fixedly connected to the bottom end of the first piston plate 16, and the plurality of groups of second elastic telescopic rods 15 are distributed in a circle between the first piston plate 16 and the inner wall of the submersible installation barrel 6, and an abutment block 17 is fixedly connected to the upper end of the first piston plate 16;

[0038] See also Figure 6 to Figure 8The sampling mechanism 201 includes a connecting tube 23, which is fixedly connected to the bottom of the sampling tube 9. The connecting tube 23 is filled with heavy gear oil, which is viscous and has lubricating properties. The bottom end of the inner wall of the connecting tube 23 is fixedly connected to the third elastic telescopic rod 22, and the output end of the third elastic telescopic rod 22 is fixedly connected to the second piston plate 27. A plurality of liquid permeable holes 8 are opened inside the second piston plate 27. The plurality of liquid permeable holes 8 are distributed circumferentially in the second piston plate 27, and the aperture of each group of liquid permeable holes 8 is very small. Therefore, when the second piston plate 27 moves in the inner wall of the connecting tube 23, since the aperture of the liquid permeable holes 8 is very small and the heavy gear oil is a viscous liquid, the heavy gear oil inside the connecting tube 23 can have a deceleration effect on the second piston plate 27 when passing through the interior of each group of liquid permeable holes 8. The plurality of liquid permeable holes 8 are distributed circumferentially in the second piston plate 27. When the second piston plate 27 is in the connecting tube 23 When the inner wall moves, the heavy gear oil in the connecting pipe 23 needs to pass through the liquid permeable holes 8. Due to the limitation of the aperture of the liquid permeable holes 8 and the viscosity of the heavy gear oil, the aperture of each group of liquid permeable holes 8 is small, so that the heavy gear oil will encounter greater resistance when passing through. This resistance will hinder the movement of the second piston plate 27, thereby effectively reducing its movement speed, achieving the second piston plate 27. The deceleration effect is achieved, each group of second piston plates 27 is fixedly connected to the corresponding abutting circular plate 14 by a second pull rope 11, a sampling port 20 is provided on the outer wall of the sampling tube 9, and a sampling liquid storage bottle 24 is arranged inside the sampling tube 9, and the mouth of the sampling liquid storage bottle 24 abuts against the sampling port 20, the upper end of the sampling tube 9 is rotatably connected with a flip cover 29 through a rotating shaft, a reset torsion spring is connected between the flip cover 29 and the sampling tube 9, a folding shrink tube 19 is fixedly connected to the mouth of the sampling liquid storage bottle 24, and the outer wall of the folding shrink tube 19 is provided with a plurality of corrugations, which can be pulled and folded at will, does not occupy space, is simple and convenient The end of the foldable shrink tube 19 close to the sampling port 20 is fixedly connected to the outer wall of the sampling port 20 with a magnetic ring 21, and the two groups of magnetic rings 21 are magnetically attracted to each other. When the bottle mouth of the sampling liquid storage bottle 24 needs to be docked with the sampling port 20, the two groups of magnetic rings 21 are magnetically attracted to each other, making it easier and more convenient for the staff to install. When the sampling liquid storage bottle 24 needs to be taken out, it is only necessary to rotate the flip cover 29 to take out the sampling liquid storage bottle 24. The outer wall of the sampling liquid storage bottle 24 is fixedly connected with a rubber pad, which can effectively enhance the sealing between the sampling liquid storage bottle 24 and the sampling tube 9.

[0039] See also Figure 6 to Figure 8The upper end of the sampling liquid storage bottle 24 is fixedly connected to a sewage detector 18, and the sewage detector 18 adopts an XY-SND1 portable concentration detector. The outer wall of the sewage detector 18 is fixedly connected to a probe pen 25 through a pipeline, and the probe pen 25 is located inside the sampling liquid storage bottle 24. The end of the sampling tube 9 close to the sampling port 20 is slidably connected to two groups of abutment plates 30, one group of abutment plates 30 is fixedly connected to the second piston plate 27 through a third pull rope 26, and the two groups of abutment plates 30 are symmetrically distributed up and down, and the two groups of abutment plates 30 are fixedly connected to each other through two groups of connecting strips 31, and the two groups of connecting strips 31 are symmetrically distributed front and back. Specifically, one end of the sampling tube 9 close to the sampling port 20 is fixed Two groups of slide bars 41 are fixedly connected, and the abutment plates 30 are slidably connected to the outer wall of the slide bars 41. The inside of the abutment plates 30 and the outer wall of the slide bars 41 are coated with lubricating oil. When the abutment plates 30 move on the outer wall of the slide bars 41, the slide bars 41 can limit the abutment plates 30 and also have a guiding function, thereby improving the stability of each group of abutment plates 30 when moving. The lubricating oil can also reduce the friction between the abutment plates 30 and the slide bars 41, thereby extending the service life of the slide bars 41. One group of abutment plates 30 is fixedly connected to the outer wall of the submerged installation barrel 6 through a fourth elastic telescopic rod 32;

[0040] See also Figure 9-10 The outer wall of the limit frame 33 is fixedly connected to a fixing plate 36, and the outer wall of the fixing plate 36 is rotatably connected to a second recovery wheel 37 with a reset function through a rotating shaft. Specifically, one end of the fixing plate 36 close to the second recovery wheel 37 is fixedly connected to a mounting round box 38, and a force storage torsion spring 42 is fixedly connected inside the mounting round box 38, and a clamping wall 39 is arranged in the middle of the force storage torsion spring 42. One end of the second recovery wheel 37 close to the force storage torsion spring 42 is fixedly connected to two groups of clamping bending blocks 40, and the two groups of clamping bending blocks 40 are symmetrically distributed at the upper end of the second recovery wheel 37. The force storage torsion spring 42 is clamped between the two groups of clamping bending blocks 40.

[0041] The working principle of the present invention is:

[0042] When the present invention is used, the installation base 1 is moved to the center of the wellhead, and the counterweight block 7 is suspended above the wellhead. At this time, the driving motor 3 is started, and the driving motor 3 drives the first pull rope 5 through the first recovery wheel 4. The first pull rope 5 releases the submersible installation bucket 6, and the submersible installation bucket 6 moves into the well. It is worth noting that it is necessary to inflate the submersible ball 10 through the inflation valve. When the submersible ball 10 expands, the submersible ball 10 drives the fourth pull rope 12 to pull the second recovery wheel 37, and the fourth pull rope 1 2 is very thin, and will not affect the measurement data after winding. When the fourth pull rope 12 drives the abutment wheel 34 to rotate, the rangefinder 35 can measure the number of rotations of the abutment wheel 34. Assuming that the circumference of the abutment wheel 34 is 50MM, when the measuring distance is 5000MM, it means that it has rotated 100 times. When it rotates to 100 times, the water depth of 20M can be measured, and when it rotates to 150 times, the water depth of 30M can be measured. Every fifty times, the water depth can be increased by 10M each time, and it increases successively;

[0043] When the submersible installation barrel 6 completely falls into the water and reaches a certain water depth, the water pressure will evenly squeeze the outer wall of the submersible ball 10, and the gas inside the submersible ball 10 will enter the submersible installation barrel 6. The first piston plate 16 will drive the abutment block 17 to abut the first group of abutment circular plates 14, and the abutment circular plates 14 will release the pull on the second pull rope 11. At this time, since the second pull rope 11 has no tension, the third elastic telescopic rod 22 shrinks toward the inside of the connecting tube 23, and the liquid permeable hole 8 is very small. Therefore, when the second piston plate 27 moves in the inner wall of the connecting tube 23, since the aperture of the liquid permeable hole 8 is very small, the first elastic telescopic rod 13 When the internal heavy gear oil passes through each group of liquid permeable holes 8, it can have a decelerating effect on the second piston plate 27, so that the second piston plate 27 will be pulled slowly by the third pull rope 26. When one group of abutment plates 30 is separated from the abutment with the outer wall of the sampling port 20, the abutment plates 30 descend slowly, leaving the sampling port 20 with enough time to collect the sewage at the current depth. When the other group abuts with the sampling port 20, the plugging and closure are completed, and the dive continues. According to the same working principle as above, it can be known that sewage at different depths can be sampled, and after sampling, the sewage can be tested by the sewage detector 18;

[0044] When the sampling is completed, the driving motor 3 will pull back the first pull rope 5 through the first recovery wheel 4. When the submersible installation barrel 6 moves up, the submersible ball 10 will gradually expand due to the reduced water pressure. At this time, the gas inside the submersible installation barrel 6 will return to the inside of the submersible ball 10. When the abutting circular plate 14 is disengaged, the abutting circular plate 14 will drive the second pull rope 11 to pull the third pull rope 26 through the second piston plate 27. Since the second piston plate 27 is reset, the fourth elastic telescopic rod 32 will drive all the abutting plates 30 to reset. It is worth noting that when the two groups of abutting plates 30 exchange positions, since the sampling liquid storage bottle 24 is already full of sewage at this time, the outside water cannot enter, so it will not affect the sampling data. According to the above working principle, it is gradually reset;

[0045] When not in use, it is only necessary to discharge the gas inside the submersible ball 10 through the inflation valve. At this time, the force-storage torsion spring 42 releases the stored force, and the force-storage torsion spring 42 will drive the two sets of clamping arc blocks 40 to rotate through the clamping wall 39. The clamping arc blocks 40 will drive the second recovery wheel 37 to rotate, and the second recovery wheel 37 will recover the fourth pull rope 12.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
